Different promotion rates for men and women are one of the main causes of the gender pay gap. The document shows that male managers are 40% more likely to be promoted than female managers who have stayed with their employer for five years. As a result, women are under-represented in senior positions and earn less, with the gender pay gap increasing the higher the position. The data presented found that between 2015-2016, 14% of men were promoted compared to 10% of women.
